Specification of Letters Patent.

ketenteo. May 14, 1907.

Application filed February a, 1904. Serial 1%. 192,277.

To all whom/1Z2? may concern:

Be it known that I, HOWARD R. SARGENT, a; citizen of the UnitedStates, residing at Schenectady, county of Schenectady; State oi New York, have invented certain new and useful Improvements: in Lamp--'lri.nimings, y of which the iollcwing isa specification.

My present invention relates to trimmings or iii gs particularly adapted for use in comics .on with electric lumps though not united to such use.

The various novel features of construction. and arrangement which characterize my invention are pointed out with particularity in the cleirrs anneXed to-anll forming: at part of this specification. Y i

For a better understanding of my invenlion, hmvever, reference may be had to the.- zuzcmnpanying drawings. and description. in

which. i have illustrated and. described one form in which it may be embodied.

Figure 1 is an elevation with parts in section and parts broken away showing an electric lamp equipped. with my invention, and Fig. :2 is a sectional. elevation of the fitting.

llclf'erring to the drawings, 1 represents a socket such as that ordinarily employed. to receive incandescent electric hnnps. The

socket is formed with an annular head 2 locaterl slightly above the lower curl of the shell of the socket. A lamp 3 is sccureil in. tie socket 1 in any suitable manner as by a threerlcrl. crmnection. The globe l of the lamp is shown'in. the drawings as approxi lnetely spherical. The lower portion. of the globe may be frosted as shown. A. portion er the upper surface of'tbe globe, preferably unfrostcrl, is covered by the zonuler portion of e reflector Jinoniber 5 which may be iormecl out of sheet metal or other suitable opaque or translucent material. I

An expansible collar or fitting oxextenrls between the head 2 and. the reflector mem her 5. in the form of my invention shown in tire drawings the collar 6 comprises ennule shell members 7 and 8, which maybe forme out of spun metal, and a helical spring 9.

"ihe shell member 8 comprises a portion 10 so shaped that each sectioncut by a plane passing through the axis of the member is outwardly in the form of an. outwardly 0011". The portion 3.1 of the member 8 immediately above the portion 10 Is cylinis forrne cl at the upper end of the portion 11.

The flange portion 12 tcrn'iinates in an upwardly extending cylindrical portion 13.

' T he member 7 is formed with e cylindrical portion. 14 which surrounds the cylindrical portion 13 of the member 7. The extreme lower portion of the member 14 is in the form of aninwerdly turned flange portion 1.5,the inner periphery of which may closely cmbrace the cylindrical portion 11 of the n1ember S. The upper portion 16 of the member 7 is curved so that each section cut by a plane passing through the axis of the member is in the lorm ofan ogce curve the lower part or" the portion 16 being practically radial. The opening 17 formed at its upper end is just large enough to receive the lower end of the Socket 1.

The helieel spring 9 extends between the lower radial part of the curved portion 16 of the IUGIILA'JQX '7 and the radial portion 12 of the member 8 nnrl t 'rrls to separate the portions '7 and S to the extent shown in. Fig. 2.

The various parts are so proportioned and, arranged that when the lamp 3 is secured in the socket 1 the members 7 and 8 will be telescoped. together somewhat between the bead 2 of the socket 1 and the reflector member 5.

llml'er these circumstances the spring 9 serves to firmly secure the parts together with the reflector 5 in proper position with respect to the globe at.

'l use of the elastic collar 6' obviates the necessity of marking nice calculations in proportioning tl'w parts. The collar also serves conceal and protect the upper portionof the lame and f" lowerenrl of the socket.

.lt will, of use, he understood that the particular shapes giren to the various parts of the collar ere not essential features of my invention. l contemplate that various (levietions can he made in. the form. and arrangement of the parts employed in. the construcrlricnl. fin outwardly extending flange 12 A secured in seiil socket, en annular or zone extending between said socket and said re- 111g against the globe of said lam Elector comprising two annular members ca peble of innit-ed relative movement and a -s mm tendin to so )QI'ELLG said members.

4. In con'ibination, a socket, a lamp see cured in said socket, {i reflector for sold lamp resting against a port-ion of its surface, {ind a collar formed of telescoping sections ex. ending between said reflector and said socket.

5. In con'ibinetion, an electric lamp globe or bulb, e zonulsr reflector through the opening in which "the 'neck of said bulb is passed, and resilient means vfor pressing said reflector against said globe.

6. In combination, a socket, on electric lamp secured in. said. socket, areflector restp, and resilient means extending between said socket and. salt reflector to hold the letter against the said globe.

7. In combination, a lamp socket, a lamp bulb the neck of which. is secured in said socket, s reflector having an opening through which the neck of the lamp bulb passes, and a resilient collar one end ofwhich engages the lamp socket and the other end of which engages the reflector,

8. In combination, on electric lamp globe or bulb, a reflector substantially circular in outline formed with a centrally located aperture through which the neck of the bulb or globe is passed, and resilient means for pressing the reflector against thelarnp globe.

9. In combination, allamp socket, clamp bulb the neck of'wqrich is secured in said socket, e reflector substantially circular in outline and formed with ix'centrall located aperture through which the neck 0 the bulb is passed, and an extensible collar extendin between said socket and said reflector to hol said reflectors ainst the lam ,bulb. i
